19 Claims.

This invention. relates to paper carriage equipment for calculating machines. It relates particularly to a mechanism which may be termed, for convenience, an automatic predetermined, delayed, and/or intermittent skip tab mechanism. It is automatic because, after the operator sets the machine in operation, the machine will go through a series of operations without requiring any attention. It is delayed because, even though the skip mechanism is set, the skip tabulation need not and generally does not occur until after a number of operations of the machine. It is predetermined" because the operator can set the machine to cause the skip tabulation to occur in any predetermined column or columns. It is intermittent in that a skip tabulation may occur at two or more different places in the movement of the carriage across the machine. The nature of the invention will be more clearly understood by first explaining some of the work that is performed.

In some classes of work, particularly the writing of public utility bills, it is often desirable to print an item in a number of difierent columns on the bill or form. Repeated printing of the same item can be obtained by providing the machine with ,an automatic repeat mechanism such as shown, for example, in Muller Patent No. 1,397,774. This causes the machine to autonumber of times during which operations the paper carriage moves from column to column across the machine so that the item entered on the amount keys is printed in diflerent columns on the form in the paper carriage. In the examples of work shown in Figs. 7 and 8, the first line of entries illustrates an operation in which the entry $25.00 is repeated eight times and entered in each of eight successive columns.

It is sometimes desirable to repeat an entry several times, but to skip predetermined columns on the form. Fig. 7, for example, shows in the second line an entry which is repeated twice in columns 2 and 3, after which columns 4 and 5 are skipped. The entry is again repeated in columns 6, 7 and 8. Another type of entry is shown in line 2 of Fig. 8 where the item is repeated in column 2, column 3 is skipped, the item is repeated in columns 4 and 5, column 6 is skipped, and the item is again .repeated in columns 7 and 8.

If the operator were to operate the machine by depressing the motor bar for each columnar position of the carriage it would be a simple matter to skip the desired columns by the use of a matically repeat its operation a predetermined.

skip tab key such as ,shown for example in Rinsche Patent No. 1,580,534, but, in the writing of bills such as above described, it is not desired to follow the cumbersome practice of having the operator manipulate the motor bar for each op- 60 eration of the machine. Instead, themachine should be such that the item can be entered in the first column after which the machine continues to operate automatically without any further attention on the part of the operator. This requires that the skip tab operation be controlled automatically, that it be delayed until the proper columns are reached; that it be constructed so that the columns to be skipped can be predetermined, and that the skip operations be 7o intermittent if desired. If tappets on the paper carriage were to be usedby themselves to control the tabulation; the difliculty is that the carriage would skip the same columns during each of its movements across the machine whereas, in practice, it may be desired to skip certaincolumns only for certain lines of entries. The present invention is directed to a solution ofthis problem.

An object of the invention is to provide improved automatic skip tabulation mechanism for the paper carriage of a. calculating machine.

A more particular object is to provide a mechanism of the class described which is normally inactive but which maybe automatically set by the operator at the time he sets the machine into operation after which the skip tabulation will be taken care of automatically without any further attention. r

Other and more' specific objects will appear from the following specificationand drawings.

An embodiment of the invention is shown in the ace ampany n drawings in which:

The invention is shown applied to a Burroughs high keyboard type of machine, the construction of which is'well-knownso that only a brief description will be given here. It is to be understood, of course, that the invention can be applied to other types of machines.

General calculating machine features The machine is provided with a plurality of depressible amount keys 10 on which items may be entered. As the machine is operated, type bars 11 move to positions corresponding to the keys depressed after which a printing mechanism operates to print the item on a sheet or form 12 positioned about a platen P on a traveling paper carriage designated generally by the letter C. When the machine is motor-driven it is set into operation by depressing a motor or starting bar 13 that rocks a lever 14 counterclockwise as viewed in Fig. 1. A second lever 15 connected to the motor bar and to lever 14, is rocked clockwise. The lever 14 is connected by a spring 16 to a vertical link 17 that is connected at its lower end to an arm 18 that controls a clutch which, when the motor bar is depressed, cause the motor 19 to give the machine a stroke of operation. As the machine operates throughits forward stroke, a full stroke sector 20 pivoted at 21 moves counterclockwise to the limit of its movement after which, during the return stroke, it returns clockwise to normal. This sector carries a stud 22 positioned to engage a shoulder 23 on the vertical link 17. The parts are positioned so that, shortly after the machine starts to operate, the stud 22 engages the shoulder 23 and forces the link 17 downward to normal position, which movement normally aids in raising the motor bar 13 to normal position. A latch 24 normally engages over a stud 25 on the lever 14 to hold the lever in the counterclockwise position to which it is moved by depression of the motor bar. This would tend to hold the motor bar depressed were it not for a mechanism that is provided to automatically release the latch during each normal operation of the machine. This mechanism is as follows:

A lever having three arms 26, 27 and 28 is pivoted at 29 and urged clockwise by a spring. The lower arm 26 limits against the full stroke sector 20. The rear arm 27 carries a pass-by pawl 30 adapted to engage a stud 31 on a release lever 32. The upper end of the lever 32 engages a slide 33 having a lug 34 positioned to engage the upper end of the latch 24. As the machine starts to operate, the full stroke sector 20 moves away from the arm 26 of the three-armed lever whereupon said lever is moved clockwise from the position of Fig. 1, until the pass-by pawl 30 passes the stud 31. Upon the return stroke, the full stroke sector'20 picks up the arm 26 and moves the three-armed lever counterclockwise whereupon the pass-by pawl 30 camming against stud 31 rocks the lever 32 counterclockwise and moves the slide 33 forwardly to release the latch 24.

The'qrepeat operations of the machine are caused to take place automatically under the control of the paper carriage and for this purpose the carriage is provided with suitable rolls 40 (Fig. 1). As the carriage moves to columnar position from which a repeat operation is desired, the roll 40 depresses a lever 41 which, through suitable connections not shown in detail, causes a bell crank lever 42 to rock clockwise to move a slide 43 to the right as viewed in Fig. 1. This slide carries a projection 44 which, when the slide is moved rearward, moves under a stud 45 on the arm 27 of the three-armed lever 26, 27, 28. When the machine is operated with the parts in this position the three-armed lever is blocked against full movement in a clockwise direction, the parts being proportioned so that the pass-by pawl 30 does not pass the stud 31. Consequently, upon the return stroke, the pawl 30 will not cam the stud 31 and the lever 32 will not'be rocked. This means that the slide 33 will not be moved forwardly and hence the latch 24 will not be released. The rocking of lever 32 also controls the release of the amount keys in the well-known manner and the amount keys thus remain depressed for a repeat operation so that the item first set up remains set up in the machine.

When the lever 14 is latched against return, the vertically movable link 17 may, nevertheless, be moved downwardly because of the pin and slot connection between said link and lever. However, the downward movement of the link tensions the spring 16 and, upon the return movement of the full stroke sector 20 when the stud 22 moves away from the shoulder 23, the tendency would be for the link 17 to rise immediately to cause the motor to give the machine a stroke of operation before the first return stroke of the machine had been completed. In order to prevent this a latch 46 is provided that swings down over a stud 47 on the link 17, so as to momentarily prevent upward movement of the link 17. In order to release this latch the slide 43 isprovided with an upstanding end 48 (Fig. 2) adapted to engage a stud 49 on the latch 46. When the slide 43 is moved rearwardly the latch 46 is rocked counterclockwise as shown in Fig. 2 so as to free the link 17. This occurs at the end of an operation of the machine as the carriage moves from one position to another.

Tabulating mechanism The paper carriage moves from one columnar position to the other under the control of a tabulating mechanism which will be briefly de-,

scribed.

Referring to Fig. 1, the paper carriage supports a tabulating bar 50 to which are fixed a number of stops 51, there being a stop for each columnar position of the carriage. The bar is urged counterclockwise '(Fig. 1) against a limit stop by means of a spring 52 that acts on a' pivoted lever 53 having a forked end engaging over a stud on a projection on the tabulating bar ment 55. Near the end of the return stroke of the machine, the active stop 51 is raised above the abutment 55 which permits the carriage to move to the right (Fig. 3) until the next stop 51 strikes .the abutment, the bar 50 having, in the meantime, returned to normal position. The

active stop 51 is moved upward by means of a pawl 56 (Figs. 4 and 5) pivoted on the end of a reciprocating slide 57 that is moved upward near the end of the return stroke of the machine. The end of this pawl is directly under the active stop so that when the slide 57 is raised, the 'stop is raised and the tabulating bar rocked. The slide 57 is raised by means of a lever 58 shown in Fig. 1 that is rocked at each operation of the machine by a cam 59 connected to the operating mechanism of the machine. The slide also operates the line spacing mechanism for the platen. The construction of the mechanism for operating slide 57 is well known in Burroughs machines. The operation is such that the slide 57 is moved upward near the end of the operation of the-machine.

Cushioning mechanism is associated with the abutment 55, the cushioning effect being obtained by mounting the" abutment on a stud 60 (Fig. 6) that is slidably mounted in a slot 61 in the back plate 62 of the machine. Connected to the stud 60 is a link 63 shown in dotted lines in Fig. 3 which is also connected to av lever 64 that, in turn, is connected to a dashpot 65. A spring 66 urges the link 63 and the abutment to the left.

When one of the carriage stops 51 strikes the abutment 55 it is moved to the right against the tension of the spring 66 and against the action of the dashpot 65. The stud is also supported by a sliding link 67 mounted on a stud 68 on the back plate of the machine.

Improved skip tabulation mechanism The mechanism by means of which an automatic delayed sk p tabulation of the carriage may be secured, which skip tabulation may be intermittent if desired, can be best described by beginning with the description of the means by which such mechanism is set or conditioned for operation. 1

Referring to Fig. l, a skip tab key or bar '10 is provided which overlaps the motor bar 13 and is connected by a lever '71 with the lever 15 associated with the motor bar, the whole construction being such that, when the skip tab bar or 1 key 70 is depressed, the motor bar is also depressed and, when themotor bar is returned to normal, the skip tab key is also returned to normal. When the machine is provided with the automatic repeat mechanism heretofore described, it will be evident that, upon depression of the skip tab key, the machine will be set into operation after which it will continue to operate for as long as the repeat mechanism is set.

The skip tab key has a relatively long downwardly extending stem 72 connected to one arm of a pivoted bell crank lever '73 whose other arm is connected to an arm '74 fixed to the shaft 75 extending under the machine. This,

shaft has a rearwardly projecting arm 76 connected to a link 7'7. The upper end of link 7''! is connected to one arm of the bell crank lever 78 (Fig. 3) whose other arm is adapted to bear against a stud '79 on a slide 80 mounted on the back plate of the machine, the slidebeing urged to the left, as viewed in Fig. 3, by a spring 81. It will be evident that, when the skip tab key is depressed, the bell crank '13 (Fig. 1) will be rocked counterclockwise, the arm 74 will, likewise, be moved counterclockwise, and the arm '76 will'be moved downwardly to pull the link '77 downwardly. This will rock the bell crank lever '18 clockwise and move the slide 80 to the right as viewed in Fig. 3.

is a pawl 82 urged clockwise by a spring 83. When the slide 80 is moved to the right from the position of Fig. 3 to that of Fig. 4, the lower armried on a shaft on the paper carriage. Whenthe carriage moves tothe right in Fig. 3 the roll 89 engages the pass-by pawl 88 and rocks the bell crank lever 86-85 counterclockwise. Upon return movement of the carriage, the pass-by pawl 88 yields without moving the bell crank.

If the bell crank 85-86 is rocked counterclockwise after the slide 80 has been moved to its Fig. 4 position, the stud 84 engaging the lower portion of the pawl 82 rocks the pawl clockwise. The upper end of pawl 82 is positioned to engage a stud 91 on a slide 92 mounted on-a stud 93 on the back plate of the machine. the slide being urged to the left as viewed in Fig. 3 by a spring 95. This slide is supported at its right-hand end by a stud 94 operating in I a.slot in a second slide 99. The slide 92 has a downward projection 96 connected by a spring 97 to a downward projection 98 on the slide 99,

the latter being mounted on the studs 93 and 111. This second slide 99 has a'cam nose 100 (Figs. 4, 5 and 6) adapted to engage a V-shaped notch 101 in the end of the abutment 55. For the purposes of the present invention the abutment 55 is pivoted on the stud 60- (Fig. 6) so that it may be swung from the "position of Figs. 4 and 5 to that of Fig. 6, the abutment being urged in the position of Figs. 4 and 5 by a spring 102.

The notch 101 in the abutment is located relative to the cam nose 100 of the slide 99 so that,

when the cam nose engages the notch, the tendency is for the nose to cam the abutment downwardly to the position of Fig. 6.

When the bell crank 85-86 isrocked counterclockwise by the roll 89 on the carriage, the pawl 82 is rocked clockwise which moves the slide 92 to the right. This slide, acting through the spring 97 yieldingly pulls the slide 99 to the right and the cam nose 100 engages the notch 101 in the abutment 55. As long as one o! the stops 51 is in engagement with'the abutment 55, the abutment is not moved downwardly by the above-described operation because the fric- 'tion between the stop and the abutment is too great to permit this but, as soon as the stop 51 is raised by pawl 56 to free the abutment, the abutment is 'moved downwardly to the position of 6 where is out of the path of the next stop 51 on the tabulating bar of the carriage.

When the slide 92 is moved to the right to move the slide 99 to move the abutment 55 downward, the slide 92 is'latched in its moved position by a latch 103 in the form of a bell crank lever,

one ,arm of which has a nose 104 engaging over a stud 105 on the slide 92. The abutment 55 is thus latched downward out of the path of the tabulating stops on th carriage so that the carriage is free to move to the right. The number of columns that will be skipped is predetermined by the location of an adjustable tripping tappet on the bar 50. This tappet projects for- "wardly farther than the regular stops 51 and is shaped so as not to interfere with the regular operation of the carriage. The nose of the tappet is positioned so as to engage the yielding upwardly projecting arm of the bell crank latch Pivoted on the right-hand end of the slide 80 103 and trip it, a pass-by pawl 112 being positioned on the upper end of the latch to permit the carriage to return without tripping the latch.

When the desired number of columns have been skipped, the tappet trips the latch 103 thereby releasing the slide 92 which is immediately moved to the left by the spring 95. This moves the slide 99 to the left and releases the abutment which, in turn, is moved upwardly by its spring 102 so that the abutment is in position to engage the next stop 51 to arrest the movement of the carriage.

The movement of the slides 92 and 99 and of the abutment 55 to normal position does not return the skip tab key to normal as it is held down as long as the motor bar is held down under the control of the automatic repeat mechanism. This means that the slide remains in Fig. 4 position with the lower portion of the pawl 82 under the stud 84, so that the parts remain in position for other skip tab operations. If another roll 89 is provided on the shaft 90 on the paper carriage, the bell crank 86 is again rocked and a, skip tab operation takes place the same as above described, the number of columns skipped depending upon the location of the second trip tappet 110. As many of these skip tab operations as is desired may thus be obtained with any number of regular tabulations between them. In other words, an intermittent skip tabulation is obtained.

Operation Although the operation of the machine will be fairly clear from the description already given, an operation will be briefly followed through.

forms and the operator rarely has to pay anyattention to them as the machine is generally employed to write a large number of forms that are approximately alike.

The machine may then be used to repeat an item in every column by simply depressing the motor bar 12, the carriage being provided with a suflicient number of rolls 40 to cause repeat operations to take place for the desired number of columns.

If it is desired to skip certain columns the operatcr, instead of depressing the motor bar, depresses the skip tab key 70. This causes the machine to operate and at the same time moves the slide 80 (Fig. 3) to the right so that the lower portion of the pawl 82 is positioned under the stud 84 as shown in Fig. 4. No skip tabulations take place immediately during operations of the machine. When the carriage reaches the column from which it is desired to skip a succeeding column or columns, the roll 89 engages the pass-by pawl 88 and rocks the bell crank lever 85-86 counterclockwise. This moves the slides 92 and '99 to the right, the nose of slide 99 moving into engagement with the abutment 55. When the stop 51 is raised from the abutment, after-the printing operation in this columnar position of the carriage, the cam nose 100 moves further into notch 101 and the abutment is cammed downwardly out of the path of the next stop 51 with the result thatthe carriage moves to the right for a predetermined number of columns, the arrest of the carriage depending upon the location of the trip tappet 110. When this trip tappet comes into position to trip the latch 103, the slides 92 and 99 and the abutment 55 move back to normal and the carriage is arrested. The skip tab key remains depressed and the lower portion of the pawl 82 remains under the stud 84 in position for another skip tab operation. When the next roll 89 comesinto position to engage the pass-by pawl 88 another skip tab operation occurs for a desired number of columns determined by the location of the second trip tappet 110. i

From this it will be seen that skip tabulation is obtained automatically; it is delayed for any desired number of columns, and two or more skip tabulations may take place at predetermined points and for predetermined numbers of columns throughout the length of travel of the carriage. The operator need pay no attention to the machine except to depress the skip tab key after which all other operations may take place automatically.

It is to be understood that the structure shown is for purposes of illustration and that variations may be made in it without departing from the spirit and scope of the invention as defined by the appended claims.
